In the state of shape, the main part 51 of temperature sensor 50 is inserted from the top of sensor maintaining part 30, and make it along arrow X
Shown direction movement.So, the spring 53 of temperature sensor 50 is guided by the inclined plane 38A of protective bulkhead 38, and
The lower surface of main part 51 is guided by the inclined plane 35A of the bottom wall 35 of sensor maintaining part 30, makes main part 51 to the left side in Fig. 2
Fang Yidong.
When the locking teat 54 of the upper surface for being formed at spring 53 is abutted with protective bulkhead 38, spring 53 further to
Lower section flexural deformation.And then, the main part 51 of temperature sensor 50 is moved along direction shown by arrow X, in main part 51
End reach the position that is abutted with limiting wall 40 after, during the pressed state of the locking operating portion 55 of releasing, spring 53 is elastic
Restore, locking protuberance 54 is embedded into the locking hole 39A of protective bulkhead 38, and locking operating portion 55 enters into the recessed of protective bulkhead 38
In portion 38B, the main part 51 of temperature sensor 50 is limited to the movement in the front on installation direction by limiting wall 40.In the state
Under, as shown in Fig. 2 the main part 51 of temperature sensor 50 is configured at the downside of protective bulkhead 38 and is covered by protective bulkhead 38, and
It is engaged in the state of the bottom of main part 51 is exerted a force towards the direction contacted with the upper surface 14 of monocell 12.
Temperature sensor 50 is installed to after sensor maintaining part 30, nut is screwed to the electrode column of each monocell 12
The ridge 13C of 13B, electrode terminal 13 is connected with bus 19, and the electric wire 45 that will be connected with bus 19 is contained in electric wire receiving
During portion 41, the battery module M1 of present embodiment can be obtained.
(functions and effects)
Next, the effect and effect to present embodiment are illustrated.
In the present embodiment, the end of the electric wire 45 of the voltage detecting electrode terminal adjacent with connection by welding
Bus 19 between 13 is connected, therefore the voltage detecting terminal that need not be connected with electrode terminal 13.In addition, in this implementation
The bus 19 and the heart yearn 46 of electric wire 45 used in mode are aluminum or aluminium alloy system, thus with use copper or copper alloy system
The grade of bus 19 compared to being able to lightweight.As a result, according to present embodiment, using the teaching of the invention it is possible to provide a kind of light-weighted distribution mould
Block 10.
